CADathon

Design fast. Model precisely. Outlast the competition. CADathon is a high-pressure 3D modelling battle where speed, accuracy, precision, and problem-solving are put to the test. Recreate a reference model against the clock, then watch the top eight go head-to-head in a live 1v1 knockout, modelling the same object simultaneously.
